Topological synthesis of compliant mechanisms using multi-criteria optimization
TLDR
In this paper, a new method for topological synthesis of single-piece compliant mechanisms is presented, using a "design for required deflection" approach, which handles motion and loading requirements simultaneously for a given set of input force and output deflection specifications.Abstract:
Compliant mechanisms are mechanical devices that achieve motion via elastic deformation. A new method for topological synthesis of single-piece compliant mechanisms is presented, using a “design for required deflection” approach. A simple beam example is used to illustrate this concept and to provide the motivation for a new multi-criteria approach for compliant mechanism design. This new approach handles motion and loading requirements simultaneously for a given set of input force and output deflection specifications. Both a truss ground structure and a two-dimensional continuum are used in the implementation which is illustrated with design examples.read more
